摘 要:牛心樸子草廣泛分布于我國西北旱沙荒漠地帶,筆者發(fā)現其提取物中生物堿部位對危害極大的煙草花葉病毒(TMV)具有很高的抑制活性。生物活性跟蹤與色譜分離、結構鑒定確認該生物堿屬于菲并吲哚里西啶,活性成份為安托芬(1)和6-羥基-2,3-二甲氧基菲并吲哚里西啶(2)。此外,還分離得到另外三種生物堿。構效關(guān)系表明氮上孤電子對和菲環(huán)對高的抗病毒活性是必要的。 |

Abstract:With the aim of searching antiviral substances to tobacco mosaic virus (TMV),alkaloid extracts from the alcohol extract of Cynanchum komarovii were isolated through gel chromatograph. 7-Demethoxytylophorine(antofine,1)was present as the primary content of the alkaloid,another four alkaloids, 6-hydroxyl-2,3-dimethoxyphenanthroindolizidine(2),7-demethoxytylophorine N-oxide(3),14-hydroxyantofine N-oxide(4)and 2,3-dimethoxy-6-(3-oxobutyl)-7,9,10,11,11a,12-hexahydrobenzo[f]pyrrolo[1,2-b]isoquinoline(5)were obtained at lower levels in the extract. Among them,the known alkaloid (2) was isolated from Cynanchum komarovii for the first time. A half-leaf method was used to assess the inhibitory activity of the five alkaloids against TMV. It was found that the alkaloids 1 and 2 exhibited excellent antiviral activity and the both alkaloids were responsible for the antiviral activity of the alkaloid extracts from the alcohol extract of Cynanchum komarovii. The presence of free nitrogen in tertiary amine and phenanthrene ring were essential for high antiviral activity. |
